SYNOPSIS

DESCRIPTION

These convenience functions are used to retrieve and update class-dependent
Elf32_Cap or
Elf64_Cap information.

Argument data is an Elf_Data descriptor associated with a section of type SHT_SUNW_cap. Argument ndx is the index of the entry being retrieved or updated. The class-independent GElf_Cap structure is described in gelf(3).

Function gelf_getcap() retrieves the class-dependent entry at index ndx in data buffer data and copies it to the destination pointed to by argument cap after translation to class-independent form.

Function gelf_update_cap() converts the class-independent entry pointed to by argument cap to class-dependent form, and writes it to the entry at index ndx in the data buffer described by argument data. Function gelf_update_cap() signals an error if any of the values in the class-independent representation exceeds the representable limits of the target type.

RETURN VALUES

Function
gelf_getcap() returns the value of argument
cap if successful, or NULL in case of an error. Function
gelf_update_cap() returns a non-zero value if successful, or zero in case of an error.
